IMPROVEMENT IN SMOKE-HOUSES.

The Schedule referred to in the" Letters Patent and making part of the lame.

To-all whom it may concern:

Be a known that I, ASA wim ms, of the city and county of Providence, inthe State of Rhode Island, have invented a new and improved Smoke-House,

of which the following isa specification. In the drawingv Figure 1 is a plan taken from the point r in fig. 2. Figure 2 is a vertical central section. Similar letters denote like parts in the drawing. My invention relates to a smoke house of any suitable size or shape, which is built of brick, stone, or other non-combustible material, witlian archedroof, also of brick. i

It consists of an upper and a lower chamber, the

lower chamber containing the furnace and necessarypipes, the upper chamber containing a perforated cone,

the use of which will be hereafter explained, and a suitable number of movable beams, upon which the hams to be cured are hung.

The floor which-divides the two chambers .is pr 0 vided with openings covered by iron gratings, to admit of the passage of hot air from the lower to the upper chamber. non-combustible substance.

The furnace in the lower chamber, has a radiator on top, which spreads the heat over the two chambers thoroughly and quickly.

The smoke-pipe leads from thetop of the furnace to the upper chamber.

A perforated cone is placed over the upper end of the smoke-pipe to receive and spread the smoke in all directions in the upper, chamber.

A second pipe. extends from the outside of the house into the lower chamber, and, branching at right angles, terminates in the-upper chamber at grated openings in the floor. This pipe acts as a ventilator to the upper chamber,pure air from ,withont passing throughit into the upperchamber.

There is a damper or regulator in this pipe toregufate the amount of air admitted through the passage,

and tends to keep .the air in the upper chamber at an even temperature.

' The arched roof is provided with an opening of suit- -Ee size and shape, to-let oh the impure air and su- "duous smoke.

This floor is constructed of brick or any A fire being built in the furnace F, all the smoke passes through the pipe S into and through the peri'orated cone 0, taking the directions. indicated by the arrows in figt2.

The heat-thrown oh by the radiator E passes into the chamber A through the gratings e e c e.

The regular d being opened, the airfrom without 1 passes through the pipe V and grating c 0 into the chamber A.

The impure air and superfluous smoke passes out through the opening it in the arched roof.

The advantages which I claim in a smoke-house constructed in this manner are-- First, perfect security from all danger of fire.

Second, that hams cured in this house are perfectly sweet, and have a bright, clean appearance not to be obtained by any other smoke-house.

Third, that they can be cured in one-half the time taken by any other process.-

Having thus fully described 'my invention,

What I claim as my invention, and desire to secure by Letters Patent, is-

A smoke-house constructed as described, consisting of an upper chamber, A, with its movable beams a a a, perforated cone 0, ventilator n, and'gratings c c, e e e c, together with a lower chamber, B, containing a furnace, as E, with its radiator E, a smokepipe, as S, and the branching ventilating pipe V with its regulator d, as herein setforth,and for the purpose Witnesses: ASA WATERMAlT.
